The growth of InAs epilayers on GaAs substrates has been a subject of intense studies over the past few years, due to important device applications of such layers in optoelectronics. In the field of high-speed infrared detectors, InAs is especially attractive as an absorption layer, due to its narrow band gap and high electron mobility. On the other hand, a semi-insulating GaAs is very convenient as a substrate, due to its transparency. However, the large lattice mismatch (7.3%) between InAs and GaAs causes major problems in obtaining high quality material.
